Oil Skimmer for a Large Food Producer


THE PROBLEM:

A facility producing salad dressings and other liquid sauces was struggling with high FOG loadings that were overwhelming it's primary DAF.  These primary DAF upsets would cause problems at downstream bioreactors and sludge dewatering system.  Limited capital was available for major improvements (ie larger primary DAF).  A simple and robust solution was needed to relieve the overwhelmed DAF.  
EVALUATION:

Salt Creek Technologies worked with facility personnel to identify potential opportunities.  The first potential solution was a floating tube skimmer.  In order to verify that the tube skimmer would adequately remove oil a small pilot unit was deployed.  The pilot proved that the concept was sound and the plant decided to move to a full scale system.

THE PROCESS:

Initially there was no obvious location where the oil was accumulating in quantities that made removal easy and efficient.  Plant personnel came up with an excellent idea to raise the influent sump level, increasing the wastewater residence time and allowing the oil to phase separate.  A significant oil layer formed that could easily be removed.

THE SOLUTION: 

Two Oil Skimmers Inc. 6V vertical tube skimmers were installed above the sump to collect the accumulated oil.  The collected oil was easily sold for a profit and the downstream equipment performances improved.  The DAF had fewer upsets and the belt press consumed less polymer.
